Exploring the barriers and incentive architecture for modifying smoke exposures among asthmatics

Area of Science:

• Public Health
• Environmental Health
• Pediatric Asthma Management

Background:

• Socio-structural barriers impede secondhand smoke exposure (SHSe) reduction for children with asthma, particularly for low-income caregivers.
• Health promoting financial incentives (HPFIs) are effective in motivating adult tobacco-reduction behaviors.
• Understanding these barriers is crucial for designing effective caregiver-targeted interventions.

Purpose of the Study:

• To assess barriers to SHSe reduction among low-income caregivers of children with asthma.
• To explore potential strategies for overcoming these barriers using HPFIs.
• To inform the design of a caregiver-targeted HPFI study for SHSe reduction.

Main Methods:

• A mixed-methods approach combining semi-structured in-depth interviews and online surveys.
• Interviews were conducted with 22 low-income primary caregivers of children with asthma in Baltimore City.
• Surveys with 56 participants provided quantitative data to supplement interview findings.

Main Results:

• Home smoking restrictions are often undermined by social pressures, necessitating targeted reduction strategies.
• Sustainable SHSe reduction is most feasible for mothers with high self-efficacy and supportive social structures.
• Preferred HPFI designs included recurrent payments contingent on reduced nicotine biomarkers and asthma education completion.

Conclusions:

• An HPFI-based study design is proposed, targeting low-income caregivers and their social networks.
• Incentives should be linked to pediatric biomarkers and asthma education for an integrated approach.
• This novel integrated strategy has not yet been applied in pediatric tobacco studies.
